The Don't Trust the B---- star made her way to Nine Zero One salon in West Hollywood for some VIP hair and beauty treatment before heading to a chic pre-Globes event on Saturday.

Starting with her hair at the shop's Colgate Optic White Beauty Bar, co-sponsored by Joico, the actress opted for a "braided up-do to show off her gown that evening," an onlooker tells PEOPLE. "After seeing a photo of her good friend Nina Dobrev, Krysten asked for a copycat look."

When it came time for beauty, Ritter went for something much more subtle, requesting a look that was "au naturel," the observer says.

Ritter, who the source says "was in a really good mood and excited about the night," chatted with a fellow salon-goer about surfing and snowboarding.

With fiancé Ben Flajnik out of town, Courtney Robertson decided to get pampered to anticipate his return.

Recently making her way into the Colgate Optic White Beauty Bar at the 901 salon in West Hollywood, the Bachelor winner got a manicure and told a guest at the salon, "I'm so excited for Ben to get back. I want to look good for him."

But getting her nails perfected was about as far as she'd go when it came to mild appearance-enhancing procedures.

"She turned down the offer because she wanted to look all-natural for Ben," the source says. "She was saying that he doesn't like when girls spray tan, but she took some of the line's products with her just to have in case."

One thing Robertson did take advantage of her during her man's absence?

"She showed up wearing wedge heels," the source says. "She was talking about how excited she was to wear them because Ben hates when she wears them since she's taller than him." – Dahvi Shira

The reality star joined Ali Fedotowsky and Ashley Hebert for a makeup appointment and some chitchat at Blushington Makeup & Beauty Lounge in West Hollywood.

"All three ladies got along so great," a source says. "The ladies were really cute together; they joked around and ... were all in very good moods – energetic and excited about being in each other's company."

After the makeup session, the women filmed a promo together for Emily's Bachelorette season which is scheduled to air during the Feb. 27 episode. – Monica Rizzo and Jennifer Garcia
